Long noncoding RNA (lncRNA) for clinical risk assessment of preeclampsia (PE) and application of lncRNA

Abstract

Long noncoding RNA (lncRNA) for clinical risk assessment of preeclampsia (PE) comprises the following steps: consulting and analyzing medical record data of a patient, and collecting placenta tissuesof a normal pregnant woman and a preeclampsia pregnant woman; preparing placenta tissue paraffin sections, and observing placenta tissue structure changes through placenta tissue pinus massoniana staining; carrying out bioinformatics analysis on the structure of the damage induced noncoding (DINO) RNA; extracting placenta tissue lncRNA, and detecting expression change of the DINO RNA; culturing human placenta trophoblasts, and screening DINO RNA interference fragments; after interfering with the DINO RNA, detecting the protein expression change of matrix metalloproteinase 2 (MMP-2); and afterinterfering with the DINO RNA, detecting the cell migration ability through a scratch test, and detecting cell invasion change through an invasion test. The lncRNA is used for preventing and diagnosing the PE. Samples are simple and convenient to obtain, no trauma is caused to a patient, and the feasibility is higher.

Description

technical field [0001] The invention belongs to the field of medical technology, and relates to a long-chain non-coding RNA used for clinical risk assessment of preeclampsia and an application thereof. Background technique [0002] Preeclampsia (PE) is a common pregnancy complication that causes multiple organ and system damage in pregnant women. It is one of the idiopathic diseases of pregnancy. Urine is the main clinical manifestation, and in severe cases, systemic dysfunction may occur. It is an important cause of maternal mortality and perinatal death. Blood, urine, fundus examination, etc. are commonly used diagnostic methods for preeclampsia, but such methods are traditional, mainly relying on the characteristic clinical manifestations of the disease for diagnosis, but usually when the diagnosis is clear, the gestational age is usually relatively large. In terms of treatment, at present, only symptomatic treatment can be used to relieve symptoms. Due to the particular...

Problems solved by technology

In terms of treatment, at present, only symptomatic treatment can be used to relieve symptoms. Due to the particularity of medication for pregnant women, there are few drugs that can guarantee both safety and efficacy; in the absence of effective treatment options, termination of pregnancy is the only measure for a complete cure , and the delivery of preterm and low birth weight babies will bring a heavy financial burden to the family
